1. Spindle speed adjustment method for CNC machining of lathe
As for mechanical gear shifting, in the main transmission system of the CNC machining of the lathe, the traditional headstock structure is greatly simplified due to the stepless speed regulation of the motor. However, due to the limitation of the spindle motor and the driving power supply, the output of constant torque is often in its low speed range. In order to enable the spindle to provide the output power of the main motor in the entire speed range as much as possible, and to meet the needs of CNC machine tools (attributes: automated machine tools) for low-speed and powerful cutting, a combination of 1 to 4 gear speeds and stepless speed regulation is often used, that is so-called segmented stepless speed regulation. The use of mechanical gear deceleration not only amplifies the output power, but also expands the range of speed regulation.
2. What are the main components of CNC machining machine tools?
Machine tool body: The design and manufacture of the machine tool body should first meet the needs of CNC machining. It has the characteristics of large rigidity, high precision, and adaptability to automatic operation. Generally, stepless speed regulation technology is adopted to make the machine tool feed movement and main drive. The speed change mechanism of the SS has been greatly simplified or even cancelled. In order to meet the transmission requirements, transmission parts such as ball screws and rolling slide rails are widely used.
In the CNC machining process, the control system issues instructions to make the tool perform various motions that meet the requirements. The shape and size of the workpiece are represented by numbers and letters in the form of technical requirements and machining process requirements. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. In order to improve productivity and meet the requirements of automatic processing, automatic tool holders and automatic fixtures that can automatically replace workpieces are also used.
3. The processing method of the failure of the service system of the CNC machining center
The fault forms of the CNC machining center service system include alarms such as abnormal alarm indicator lights on the speed unit of the CNC, blown fuses, and various protection trip switches. The CNC machining center service system is a system that provides power to the machine tool. Without the CNC machining service system, the CNC machining center cannot process the workpiece. Therefore, the CNC machining service system is very important in the CNC machining center. Once the CNC machining service system fails, the entire processing and production must be stopped.
